The problem of photon creation from vacuum in a cavity with vibrating walls is investigated. Explicit analytical solutions are found in the parametric resonance case (when the frequency of vibrations equals twice the frequency of some electromagnetic mode), both for a one- dimensional model and for a three-dimensional case. A possibility of generating hundreds and even thousands of photons in a resonance mode (with a frequency belonging to the GHz band) of a cavity with Q-factor exceeding 1010 is predicted. A significant change of the photon statistics and the rate of photons generation due to the interaction with a detector (modeled by an oscillator and a two-level atom) is demonstrated.
